Okay, I finally got to work on my truck today!!:snoop:
I pulled the head.
The MLS HG looked fine with no signs of damage or compromise! ARP 625's kept it clamped down great!
The cylinders walls all look good, beleive it or not... So not sure I actually have a bent rod or a badly broken ring, because the cylinder walls should be jacked up.
So, the next step is the pull the pan and we're just going to pull the pistons out "In Frame"....
Theory at this point is that the oil squirters not being able to fill the crown cavity with oil and/or only being pointed at the wrist pins, may have caused excessive ring wear and /or the rings lost tension...
There was definate signs of oil passing through on #2 and maybe a of couple others... There was some buildup on a couple of pistons....
But the spray patterns on the pistons looked Dead On in All cylinders ( Thank you Don ) and the Monotherms look Brand New still...Those things are bad A$$
I'm going to ship them back to Mahle so they can inspect them and the rings for their own testing purposes (They asked if I could do this for them)..... Then they'll get them back to me with a new set of rings...
I'm going to modify my Monotherms the way Chris ( Joesixpack ) did so as to be able to squirt oil at the wrist pin when at TDC and so the squirters will be shooting oil into the crown cavity when at BDC.
Like this...
This is the way they came... No oiling hole under the skirt, So you have to chose to leave the squirters pointed at the wrist pin like I did or to Drasticaly bend them outward to shoot into the hole of the cavity plates... By drilling the holes and moving the cover plates like Chris did, we can get oil to both areas...
oke:
